[AVaRICE-user] Fwd: Debugging AVR XMEGA with the Dragon

[Omar C. <cho...@gm...>]

Hello,

I am in a situation where it would be extremely helpful to be able to use
my dragon to debug an xmega256A3U.

Unfortunately, after running my avarice script (which used to work for the
AT90USB1287), I got the following error:
No configuration available for device ID: 4c0

Then I found this post:
http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&t=108389

where Jörg said (2 years ago) that there was no code in avarice to handle
this device.

Then I found also this more recent post:
http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&p=871867

and after a bit of looking through the manpage I've added the "--xmega"
flag but got a similar error.
This is the output:
AVaRICE version 2.10, Feb  8 2010 07:22:54

Defaulting JTAG bitrate to 250 kHz.

JTAG config starting.
Found a device: AVRDRAGON
Serial number:  00:a2:00:01:16:94
Reported JTAG device ID: 0x9842
No configuration available for device ID: 9842


I would like to know:
a) Are there any updates in this direction so that I can use the dragon
with the xmega?
b) What can I use to debug the xmega? I use ubuntu with avr-gcc tools, not
Windows/AS.
c) In the avarice manpage says that the atxmega128a1 is only supported
through the JTAG ICE mkII device. Will this device work for the xmegas?

Any comments are welcome.

Thanks.

Omar
